Embodiment 1

[0078] This preferred embodiment provides a UE type reporting method. In this preferred embodiment, the eNB has four cells, the carrier frequency of Cell1 is the home frequency band 3 of f1, the carrier frequency of Cell2 is the home frequency band 7 of f2, and the carrier frequency of Cell3 is f3 belongs to frequency band 5, and the carrier frequency of Cell4 is f4 belongs to frequency band 18. UE1 supports at most two carriers for aggregation.

[0079] Figure 9 is a flowchart of a method for reporting a UE type according to an embodiment of the present invention, such as Figure 9 As shown, the method includes the following steps S902 to S908.

[0080] Step S902: UE1 enters connected state through Cell1 in eNB.

[0081] Step S904: eNB initiates a capability query process to UE1, and UE1 reports the supported carrier aggregation capability as shown in Table 3-1:

Abstract

The invention discloses a UE type reporting method and device, a resource allocation method and device, UE and a base station. The UE type reporting method comprises the steps that the UE determines the parameters of the frequency band combination supported by the UE; the UE determines the UE types needing reporting according to the parameters of the frequency band combination; the UE reports the UE types needing reporting. By means of the UE type reporting method and device, the resource allocation method and device, the UE and the base station, the utilization rate of resources is improved.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a user equipment (User Equipment, referred to as UE for short) type reporting, resource allocation method and device, UE, and base station. Background technique [0002] In the Long Term Evolution Advance (LTE-A for short), in order to provide mobile users with a higher data rate, a carrier aggregation technology (Carrier Aggregation, CA for short) is proposed. In LTE, the maximum downlink transmission bandwidth supported by the system is 20MHz. Carrier aggregation is to aggregate two or more component carriers (Component Carriers, referred to as CC) (also known as serving cells) to support more than 20MHz, and the maximum does not exceed 100MHz. transmission bandwidth. In the LTE-A system, after the UE enters the connected state, it can simultaneously communicate with the source base station through multiple component carriers (also called serving cells, including...
